Title: Packet switching control method
Inventor: HOSOYA MASAHIKO
IPC: H04L12/70
Filed: 1992-01-09
Abstract: PURPOSE:To assure the transfer delay quality by processing with preference a specific packet that has a logical channel number and a logical channel group number of the high processing priority. CONSTITUTION:A sorting memory 502 stores the storing address, the logical channel number and the logical channel group number of each packet of an internal buffer memory 40.

Title: Absorbing type refrigerator
Inventor: KAWASAKI YOSHITAKA
IPC: B01J19/00
Filed: 1982-01-08
Abstract: PURPOSE:To miniaturize an apparatus, by a method wherein methanol is used as a cooling medium while a mixture consisting of lithium bromide and glycerine is used as an absorbent to prevent crystal precipitation of the absorbent and to eliminate a cooling tower. CONSTITUTION:As an absorbent, a mixture prepared by mixing lithium bromide and glycerin in a wt. ratio of 5:1 is used and a concd. solution is adjusted to about 60wt% in the concn. of the absorbent while the concn. of a dilute solution is adjusted to about 55wt%. When a refrigerator is operated in this system, if the temp. of a heating medium issued from an evaporator is set to about 8 deg.C, the temp. of methanol in the evaporator comes to about 7 deg.C, that is, vapor  pressure of about 46mm.Hg is necessary. Therefore, vapor pressure of about  46mm.Hg is necessary for maintaining a solution state of an absorber but, in a  lithium bromide-glycerin-methanol system, operation can be carried out in 55- 60wt% concn. sufficiently far from a crystallization curve C even if a solution  temp. is about 50 deg.C. In addition, if a cooler is cooled by the air, heat can be sufficiently dissipated and a cooling tower is eliminated.

Abstract: PURPOSE:To heighten heat absorbing capacity and lessen the abrasion of a brake by clamping an intermediate disc by a stator and a rotor disc at the operating time of a brake and holding the intermediate disc in the position of being brought into contact with the stator side by a holding means at the released time of the brake. CONSTITUTION:Each intermediate disc 6 is so formed as to be brought into contact with the stator 7 side at the time of normal running and stoppage, but when braking is once performed, a rotor side face 8a is linked like a clutch so as not to generate sliding between the rotor side face 8a and a rotor disc 5 and rotated integrally with the rotor disc 5, and a stator side face 8b is brought into slidable contact with a stator lining 14 so as to perform braking. In this case, frictional resistance is differentiated on either side face of the disc 6 in such a way that frictional force of the rotor side face 8a is made larger than that of the stator side face 8b. Accordingly, friction is generated between the side face 8b of a disc 9 and the stator lining 14, and frictional heat is absorbed by both the disc 6 and the stator lining 14.

Even if the speed is decelerated from the high speed navigation, the water depth of the cavitation plate 43 of the outboard motor 4 from the water surface of the retreat wave formed by the keel surface 5 is reduced, and the height of the wave which pushes back to the outboard motor side in deceleration is reduced to the height of the hull in the motor well specification. Therefore, the rising of the water surface in deceleration is reduced, and the splashing of water onto the upper part of the outboard motor 4 can be prevented.
